FASTENER FOR LED GER-'PLATES Application led February 7, 1912.

T 0 all r11/0m t may concern Be it known that I, Groen E. RoDMAN, a citizen of the United States, and a resident of Sunnyside, in the count-y of Yakima and State of Washington, have invented a new and improved Fastener for Lec ger- Plates, of which the following is a full, clear, and exact description.

This invention relates more particularly to means for securing ledger plates to the guards of mowing machines, reapers, binders, and headers, or any other grain or hay cutting machine employing as a part of its cutting mechanism guards and ledger plates.

The object in view is to provide an iinproved structure which may be quickly applied and removed, and which firmly holds the ledger plates in correct position.

A further object of the invention is the provison of an improved locking member formed with an interlocking beveled extension which fits over part of the ledger plate and which in turn is held in place by being inserted under the finger bar.

A still further object of the invention is the construction and arrangement of an improved ledger plate and guard, together' with a locking lever or fastener co-acting together for holding the ledger plate rigidly in posit-ion, but permitting an easy ready removal thereof at all times.

ln carrying out the objects of the invention the usual form of guard is provided, constructed with a socket formed for engaging the reduced end of the ledger plate. rlhe guard is also formed with a groove or way for accommodating the locking lever or fastener which co-act-s with the ledger plate for locking the same in position. The locking lever in turn is locked or clamped firmly in position by a guard bolted to the nger bar in the usual manner.

A practical embodiment of the invention is represented in the accompanying drawings forming a part of this specification, in which similar characters of reference indicate corresponding parts in all the views.

Figure 1 is a longitudinal vertical section through an embodiment of the invention; Fig. 2 is a top plan view of the structure shown in Fig. 1 with the finger bar removed and part of the guard broken away; Fig. 8 is a section on the line 4-4 of Fig. 1, the same being shown on an enlarged scale; and Fig. 4 is a top plan view of the ledger plate.

Referring to the accompanying drawings Specification of Letters Patent.

by numerals, 1 indicates a guard formed of the usual shape and substantially of the usual construction, having a socket 2 for receiving a projection or tang 3 of the ledger plate 4, and a groove 5 designed to accommodate a locking lever G. The ledger plate 4 is formed of any usual or preferred struc ture having the usual cutting edges 7 and 8 which co-act with the sickle in the usual manner, t-he sickle passing through the opening 9. The ledger plate is formed with a notch 10 having beveled walls 1.1 for engaging the overhanging wall 12 of the locking lever G. The locking lever 6 is also formed with a projection 13 for causing a better interlocking action between the locking lever and the ledger plate, as clearly shown in Fig. 1. After the ledger plate 4 and the locking lever 6 have been positioned as shown in Fig. 1, the guard 1 is then placed in posit-ion on the finger bar 14 and clamped rigidly in position by a bolt 15. By clamping the guard 1 to the finger bar 14, the locking lever 6 is held in position, because the finger bar 14 presses down on the projection 16 and against a shoulder 17.

By the construction and arrangement disclosed it will be observed that the ledger plate 4 is held rigidly in position at all times, but may be quickly removed and renewed whenever desired simply upon the removal of the bolt 15 and associated parts.

Having thus described my invention, I claim as new and desire to secure by Letters Patent 1. In a device of the character described, a guard formed with a socket and a longitudinally arranged channel, a ledger plate fitting into said socket and overlapping said channel, said ledger plate being formed with a notch having a beveled wall, a finger bar. and a locking lever fitting in said channel formed with an overhanging projection hav-r ing an under cut fitting said beveled wall of said notch, said locking lever being formed with a proj ect-ion fitting beneath the part of the ledger plate overlapping vsaid channel whereby the outer edge of said ledger plate is locked in position, A said locking lever eX'- tending beneath said finger bar whereby the same is held rigidly in said channel.

2. in a device of the character described, a guard formed with a socket and a longitudinally arranged channel, a ledger plate fitting into said socket and overlapping part of said channel, the overlapping portion of said ledger plate being formed with a beveled wall, a finger bar rigidly secured to said guard and overlapping part of said channel, and a locking lever positioned in said channel formed .with a. notch fit-ting the edge oi said finger bar whereby part ot' the locking lever projects beneath the finger bar and is clamped by the finger bar firmly to said guard, said locking lever being also.

formed with an extension fitting into that part of said channel adjacent said socket, and an overhanging projection having a beveled undercut fitting the beveled wall of said ledger plate whereby the ledger' plate is held rigidly in said socket.

3. In a device of the character described, a guard formed with a socket and a longitudinally arranged channel, a ledger plate fitted into said socket and overlapping said channel, said ledger plate being formed with a notch in the overlapping portion, a finger bar, and a locking lever fitting into said channel, said locking lever being formed with a notch at one end into which said finger bar projects whereby the locking lever is held rigidly in said channel, said locking lever being also formed with a lug near the end opposite said notch, said lug having an overlapping portion, said lug being adapted to fit into the notch in said ledger plate and overlap the walls thereof whereby the ledger plate is positively clamped in position.

In testimony whereof I have signed my nani-e to this specification in the presence of two subscribing witnesses.
